PIPE-covert.

Specification of Letters Patent. A Patented J line 24, 1919.

Applic ation filed may 3i, serial no. 237,522.

To all whom it may concern:

Be it known that I, FRED H. KLINE, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented new and useful Improvements in Pipe-Covers, ofwhich the following is a specification.

This invention relates to a protecting device for smoking pipes, andpertains especially to 'a device for covering the open mouth of thebowlof a pipe.

Tobacco pipes having the bowl open are objectionable because of thescattering of ashes and burning tobacco, resulting in burnt holes inclothing and fabrics. It is practi cally impossible for a smoker to usea pipe.

in an automobile, because of scattering of the burning contents of thepipe. It is also found that there is a comparatively large collection ofmoisture and fluid in the bottom of the bowl of an open pipe, which isdecreased by covering the mouth.

It is an object of this invention to provide a cover of the characterdescribed, which may be stamped from sheet metal, is cheap, simple anddurable in construction, and which may be applied to pipes now on themarket and in use. i

I accomplish these objects by means of the embodiment of my inventionillustrated in the accompanying drawing in which:

Figure l is an enlarged plan View of a cover before the gripping fingersare bent into final positlon. plan view of a cover ready to be lnstalledupon the pipe, the fingers having been benting, the cover comprises acircular cap portion 5, which is adapted to be disposed over the openmouth of the bowl of a pipe. The cap is preferably a flat disk, fromwhich fingers 6 and 7 are cut.- lhese fingers are Fig. 2 is an enlargedradial and extend to a point adjacent the center of the cap.

The fingers are upset from the cap, and their ends bent so that surfacesare formed which are substantially at right angles to the plane ofthecap. The cap is preferably made of resilient metal so that the fingers 6and 7 are spring fingers.

In their final position asshown in Figs. 2, 3

r and 4, the ends fall short of the periphery of the cap. Perforations 8and 9 are punched in the cap for the admission of air to the bowl. It isevident that the cap may be formed from sheet metal in one operation bymeans of a die, making a cheap and durable construction.

The cover is adapted to a particular pipe by bending the fingers 6 and 7inwardly so that their spread is a little greater than the internaldiameter of the pipe bowl. The coveris then applied by tilting it withreference to the mouth of the bowl so that one finger is disposedtherein against the inner wall of the bowl. The cover is then forceddown over the mouth with the other finger inside of the bowl, as shownin Fig. 4. The pressure of the fingers 6 and 7 against the wall of thebore of the pipe bowl holds the cover in position.

The fingersbeing upset from the cap 5 form openings for the admission ofair to the bowl. Perforations 8 and 9 are only added, when it isnecessary to increase the draft opening through the cap, and, in mostinstances, they are not necessary. Attention is particularly called tothe feature of upsetting the fingers from the cap, thereby providingfingers integral therewith and also draft openings.

The cover prevents the scattering of ashes and burning tobacco. It alsopermits the pipe to be laid upon its side without spilling hot ashes andburning tobacco. The cover is simple, light in weight, durable andcheap. It does not detract from the appearance of the pipe, and may beapplied to pipes without in any way changing their construction, marringor injuring there.

The pipe also conserves tobacco, as it pretheir free ends adjacent theperiphery of the 10 Vents tobacco burning briskly when the pipe diskbent so as to form knuckles adapted to is not being drawn upon. engageand grip the inner wall of a pipe What I claim is: I bowl.
